+@cindex composition of Guix revisions
+Sometimes you might need to mix packages from the revision of Guix you're
+currently running with packages available in a different revision of Guix.
+Guix @dfn{inferiors} allow you to achieve that by composing different Guix
+revisions in arbitrary ways.
+
+@cindex inferior packages
+Technically, an ``inferior'' is essentially a separate Guix process connected
+to your main Guix process through a REPL (@pxref{Invoking guix repl}).  The
+@code{(guix inferior)} module allows you to create inferiors and to
+communicate with them.  It also provides a high-level interface to browse and
+manipulate the packages that an inferior provides---@dfn{inferior packages}.
+
+When combined with channels (@pxref{Channels}), inferiors provide a simple way
+to interact with a separate revision of Guix.  For example, let's assume you
+want to install in your profile the current @code{guile} package, along with
+the @code{guile-json} as it existed in an older revision of Guix---perhaps
+because the newer @code{guile-json} has an incompatible API and you want to
+run your code against the old API@.  To do that, you could write a manifest for
+use by @code{guix package --manifest} (@pxref{Invoking guix package}); in that
+manifest, you would create an inferior for that old Guix revision you care
+about, and you would look up the @code{guile-json} package in the inferior:
+
+@lisp
+(use-modules (guix inferior) (guix channels)
+             (srfi srfi-1))   ;for 'first'

+;; and the old "guile-json" package.

+       (specification->package "guile")))
+@end lisp
+
+On its first run, @command{guix package --manifest} might have to build the
+channel you specified before it can create the inferior; subsequent runs will
+be much faster because the Guix revision will be cached.
+
+The @code{(guix inferior)} module provides the following procedures to open an
+inferior:
+

+Return an inferior for @var{channels}, a list of channels.  Use the cache at

+@item @code{name} (default: @code{"default"})
+A name for this Varnish instance.  Varnish will create a directory in
+@file{/var/varnish/} with this name and keep temporary files there.  If

+@cindex Git, hosting
+@uref{http://gitolite.com/gitolite/, Gitolite} is a tool for hosting Git
+repositories on a central server.
+
+Gitolite can handle multiple repositories and users, and supports flexible
+configuration of the permissions for the users on the repositories.
+
+The following example will configure Gitolite using the default @code{git}
+user, and the provided SSH public key.
+
+@example
+(service gitolite-service-type
+         (gitolite-configuration
+           (admin-pubkey (plain-file
+                           "yourname.pub"
+                           "ssh-rsa AAAA... guix@@example.com"))))
+@end example
+
+Gitolite is configured through a special admin repository which you can clone,
+for example, if you setup Gitolite on @code{example.com}, you would run the
+following command to clone the admin repository.
+
+@example
+git clone git@@example.com:gitolite-admin
+@end example
+
+When the Gitolite service is activated, the provided @code{admin-pubkey} will
+be inserted in to the @file{keydir} directory in the gitolite-admin
+repository.  If this results in a change in the repository, it will be
+committed using the message ``gitolite setup by GNU Guix''.
+
+@deftp {Data Type} gitolite-configuration
+Data type representing the configuration for @code{gitolite-service-type}.
+

+@item @code{package} (default: @var{gitolite})
+Gitolite package to use.
+
+@item @code{user} (default: @var{git})
+User to use for Gitolite.  This will be user that you use when accessing
+Gitolite over SSH.
+
+@item @code{group} (default: @var{git})
+Group to use for Gitolite.
+
+@item @code{home-directory} (default: @var{"/var/lib/gitolite"})
+Directory in which to store the Gitolite configuration and repositories.
+
+@item @code{rc-file} (default: @var{(gitolite-rc-file)})
+A ``file-like'' object (@pxref{G-Expressions, file-like objects}),
+representing the configuration for Gitolite.
+
+@item @code{admin-pubkey} (default: @var{#f})
+A ``file-like'' object (@pxref{G-Expressions, file-like objects}) used to
+setup Gitolite.  This will be inserted in to the @file{keydir} directory
+within the gitolite-admin repository.
+
+To specify the SSH key as a string, use the @code{plain-file} function.
+
+@example

+@item @code{umask} (default: @code{#o0077})
+This controls the permissions Gitolite sets on the repositories and their
+contents.
+
+A value like @code{#o0027} will give read access to the group used by Gitolite
+(by default: @code{git}). This is necessary when using Gitolite with software
+like cgit or gitweb.
+
+@item @code{git-config-keys} (default: @code{""})
+Gitolite allows you to set git config values using the "config" keyword. This
+setting allows control over the config keys to accept.

+string) was passed, a manual data entry window is opened.  The header parameter
+indicates by TRUE/FALSE (false by default) if the source @acronym{CSV} file has

+
+NSD uses zone information compiled via @command{zonec} into a binary database
+file (@file{nsd.db}).  This allows fast startup of the name service daemon and
+allows syntax-structural errors in zone files to be flagged at compile time,
+before being made available to NSD service itself.  However, most traditional
+BIND-style zone files can be directly imported into NSD without modification.
+
+The collection of programs and processes that make up NSD are designed so that
+the daemon itself runs as a non-privileged user and can be easily configured to
+run in a @code{chroot} jail, thus making any security flaws in NSD less likely

+This library attempts to be comprehensive and centralize such
+facilities.  Functions to read 16-, 32-, and 64-bit quantities from octet
+vectors in signed or unsigned flavors are provided; these functions are also
+SETFable.  Since it's sometimes desirable to read/write directly from streams,
+functions for doing so are also provided.  On some implementations,

+JavaScript.  Parenscript code can run almost identically on both the
+browser (as JavaScript) and server (as Common Lisp).
+
+Parenscript code is treated the same way as Common Lisp code, making the full
+power of Lisp macros available for JavaScript.  This provides a web
+development environment that is unmatched in its ability to reduce code
+duplication and provide advanced meta-programming facilities to web
+developers.
+
+At the same time, Parenscript is different from almost all other \"language
+X\" to JavaScript translators in that it imposes almost no overhead:
+
+@itemize
+@item No run-time dependencies: Any piece of Parenscript code is runnable
+as-is.  There are no JavaScript files to include.
+@item Native types: Parenscript works entirely with native JavaScript data
+types.  There are no new types introduced, and object prototypes are not
+touched.
+@item Native calling convention: Any JavaScript code can be called without the
+need for bindings.  Likewise, Parenscript can be used to make efficient,
+self-contained JavaScript libraries.
+@item Readable code: Parenscript generates concise, formatted, idiomatic
+JavaScript code.  Identifier names are preserved.  This enables seamless
+debugging in tools like Firebug.
+@item Efficiency: Parenscript introduces minimal overhead for advanced Common
+Lisp features.  The generated code is almost as fast as hand-written
+JavaScript.

- The normal approach to updating harfbuzz, therefore, is to pull the latest HB
- source into a scratch directory and do a local build; then copy the original
- sources AND the generated header mentioned above from the build directory into
- the mozilla tree.
- 
- If the collection of source files changes, manual updates to moz.build may be
- needed, as we don't use the upstream makefiles.
-+
-+The in-tree copy may be omitted during build by --with-system-harfbuzz.
-+Make sure to keep pkg-config version check within old-configure.in in sync
-+with checkout version or increment latest tag by one if it's not based
-+on upstream release.

+Subject: [PATCH] VP8: Fix use-after-free in postproc.
+
+The pointer in vp8 postproc refers to show_frame_mi which is only
+updated on show frame. However, when there is a no-show frame which also
+changes the size (thus new frame buffers allocated), show_frame_mi is
+not updated with new frame buffer memory.
+
+Change the pointer in postproc to mi which is always updated.

+Subject: compat/getopt: Allow non-digit parameter embedded in short option
+
+The compatibility getopt script allows only digit parameters to be
+embedded in short options. Util-linux's getopt implementation does
+not have such a restriction and allows any parameter to be embedded
+in short options. As a consequence, using the compatibility getopt
+script would choke for example on "-pab", which is a legal option
+of the "quilt refresh" command.
+
+Remove the limitation on digits so that the compatibility getopt
+script allows what util-linux allows. This fixes the second half
+of bug #54772:
+https://savannah.nongnu.org/bugs/index.php?54772
+
+As a side note, this feature of the compatibility script was broken
+anyway, as it would output the digits in reverse order.

+From: Jean Delvare <jdelvare@suse.de>
+Subject: compat/getopt: Handle a second separator
+
+getopt can be passed 2 '--' separators. The first one tells that
+getopt options are over and target program options start. The second
+one tells that the target program's options are over and following
+arguments should be treated as non-options even if they look like
+options.
+
+This second separator was not handled, causing the compatibility
+getopt script to treat the following arguments as options, eventually
+failing one way or another.
+
+Properly detect and handle the second separator. This fixes the first
+half of bug #54772:

+@item a package for calculating type areas in the way laid down by the
+typographer Jan Tschichold,
+@item packages for easily changing and defining page styles,
+@item a package scrdate for getting not only the current date but also the name
+of the day, and
+@item a package scrtime for getting the current time.
+@end itemize
+
+All these packages may be used not only with KOMA-Script classes but also with
+the standard classes.
+
+Since every package has its own version number, the version number quoted only
+refers to the version of scrbook, scrreprt, scrartcl, scrlttr2 and
+typearea (which are the main parts of the bundle).")
